If you’re noticing the SOS symbol in your status bar, it means your phone is only receiving emergency calls. This is because your cellular signal has been temporarily disrupted and you can’t make normal calls or use the internet during this time. The SOS icon is displayed to alert you of the unstable connection and that you can only call emergency service numbers when using the iPhone. It’s a good idea to contact your cellular carrier to find out more about this issue and when it should be resolved.
In the meantime, you can try disabling the SOS feature to avoid accidentally triggering it on accident. The process is quick and easy. First, you need to unlock your iPhone and open the Settings app. Then, locate and tap the icon that features a set of gears on a light grey background. You will then be able to access all the different options and customizations for your iPhone.
To disable the SOS feature, scroll down to the Emergency SOS option in the Settings app and turn off the toggles for Call with Hold and Call after Severe Crash. This should prevent your iPhone from accidentally calling 911 if you or someone else bashes the buttons on your device. This is especially helpful if you have a child who likes to bashed your phone or if you often forget to close the lid of your bag and end up pressing the side button and volume buttons simultaneously.
